摘要

导模法是一种超高熔点晶体的有效生长方法，可以生长高质量、大尺寸、高掺杂的Er∶Lu

晶体。本文测试了导模法生长的Er∶Lu

晶体的荧光发射谱及连续激光特性，在室温下获得了斜效率为23.1% 的2.85 μm连续激光输出，最高输出功率5.24 W。80 min功率RMS（Root mean square）稳定性优于1.4%，不同输出功率水平的激光光束质量

因子优于2.17。实验结果表明，导模法生长的Er∶Lu

激光晶体具备输出高功率、高效率中红外激光的能力。

Abstract

As an excellent crystal growth method， the EFG （Edge-defined film-fed growth） method is excepted to grow Er∶Lu

crystal with high quality， large size and high doping concentrations. In this letter， the fluorescence spectrum and continuous-wave （CW） laser performances of Er∶Lu

crystal grown by EFG method have been characterized. A 2.85 μm CW laser with a slope efficiency of 23.1% was realized at room temperature， and the maximum output power was 5.24 W. The RMS （Root mean square） power stability is better than 1.4% during 80 min， and the

factor of laser beam quality at different power levels is better than 2.17. The experimental results demonstrate that Er∶Lu

laser gain medium grown by EFG method has the ability to generate high output power and high efficiency mid-infrared laser.
